IS CRC SAFE TO CONSUME?
Color Remediation Column, is a purification method, making it safe to consume. To keep in mind, a finalized product, through the CRC process method, with the proper execution, will keep your smoking experience rewardingly smooth. Resulting, a technique used to refine extracts and remove impurities. Furthermore, it is a good start of an evolutionary step in the cannabis culture to be educated in “Color Remediation Column”.
WHAT DOES CRC DO?
CRC is the process of removing unwanted impurities from a hemp or marijuana extract by using a color remediation column (CRC). After color remediation has taken place, the final product will have a more appealing color, aroma, and flavor.
POSITIVE CHANGES GONE THROUGH CRC FILTRATION
- Terpenes – Uncovering a more nuanced terpene profile
- Taste – Removal of undesirable taste
- Color – Cleaner and appealing appearance
- Harmful Substances – Cleansing of unwanted substances

What is CRC?
Recently, cannabis entrepreneurs working with BHO have started to use a new backend technique called color remediation column (CRC). As an addendum to BHO extraction methodology, CRC can, in some instances, produce a cleaner, purer, more satisfying product. This is especially true if the plants used for extraction are fresh and contain a healthy mixture of cannabinoids and terpenes.
But like many powerful things, CRC BHO techniques can be used for good or ill. They can be used to manufacture good-quality cannabis extracts, or be used to mask poor-quality extracts and trick buyers into thinking they’re getting something purer, safer, and more ingredient-rich than they actually are—and that is why the merits of color remediation column technology are being hotly debated.
Why Do Companies Use CRC?
Cannabis extraction companies are noticing the numerous benefits afforded by CRC and introducing CRC into the post-processing workflow. Cannabis companies are increasingly using CRC to remove waxes, lipids, pesticides, heavy metals, toxins, and compounds that give extracts a dark color.
Filtration media used in the CRC can produce a translucent and pure extract form with the highest levels of purity and potency. CRC technology also removes the pigments in the hemp or cannabis plant that have a harsh taste when inhaled.
How To Achieve Color Remediation in BHO Extraction
Color Remediation Column
To achieve superior color remediation, a color remediation column, or CRC, is used. This ancillary piece of equipment utilizes a filter as well as filtering media such as clay, synthetic magnesium, and silica gel. The combination of the filter with these substances allows the extract to be stripped of all impurities that are left behind from the BHO extraction.

What Are the Downsides of CRC?
While not the norm, some unscrupulous cannabis producers can run low-grade concentrate through a CRC system to try and polish the extract and lighten its dark hue to pass it off as high-grade dabs. Consumers none the wiser can be duped into buying less-than-ideal extracts. As a result, the extracts end up still tasting harsh and smelling horrible.
A unique ratio of different types of filtration media is used to filter specific compounds in a single run, preferably. Improper ratios and packing practices can cause clogging, channeling, and overall loss of product and improper filtration in the CRC. Undersaturation of the filtration media can reduce the overall cannabinoid content collected and reduce the overall yield, which can drastically affect revenue for a commercial operation.
Oversaturating the filtration media can force some impurities to go through the filtration levels and end up in the final product, which can be detrimental to human health. Inexperienced CRC operators can improperly stack and pack a CRC, which can risk contaminating the final product.
POSITIVE RESOLUTION TO CRC
When it comes to optimizing the CRC process, extraction technicians must carefully calculate ratios of the different materials being used. One of the easiest ways to determine how much filtration media to use is to test the biomass, first to determine the cannabinoid content and multiply the number by the weight of the marijuana material being processed.

What Does Color Remediation Do?
Passing your product through the color remediation column adds an extra step of purification to the final product. During the BHO extraction process, some impurities may be left behind after the initial extraction and refinement process. Color remediation is an additional purification step that ensures the final product is of the highest quality.
Achieves Better Color
As the name suggests, one of the main reasons people enact color remediation is to achieve a better color in the final product. If a lower-quality plant is used, the BHO extraction process can result in a final product that has an unappealing color and a strong taste from the presence of additional undesirables such as phospholipids, terpenes, and flavonoids.
Color remediation works to remove these undesirables that cause the unattractive color, so the final product has a translucent yellow color, similar to live resin. In general, a lighter color is associated with a higher-quality product, so color remediation is often used to transform the color of a lower-quality plant, which would typically have a darker, more brown appearance.
Some see color remediation as an opportunity to mask a lower-quality end product as one that’s higher quality, which has caused some controversy in the community.
Again, a lower-quality input will result in a final product that can have an unappealing taste to some individuals. Another benefit to CRC, the same undesirables that cause poor color in a final product are also in part responsible for the resulting poor flavor. By removing said undesirables a savvy operator can improve the flavor and purity of their finished product.
